[LTP] [PATCH] open_posix_testsuite: Fix compilation issues

[Yang Xu]

Hi Zou


> Fix compilation issues:
> 1. Add the '-lpthread -lrt -lm' config into LDFLAGS
See ltp/openposix/build[1] documention, as below:

----------------------------
If you need to pass in any header locations, preprocessor definitions, etc,
   set the value via CFLAGS.
- If you need to pass in any libraries for linking, set the value via 
LDLIBS.
- If you need to pass any other values to the linker, set the value via 
LDFLAGS.
----------------------------

I guess we should use LDLIBS.

Also, do we must specify three '-lpthread -lrt -lm' configs into this?
Some case only needs one lib, such as functional/timers/timers .  I 
guess we can only add LDLIBS in case directory such as 
functional/timers/timers because generate-makefiles.sh will load libs 
from current directory.

ps: I will test this patch by using travis.
